Application filed Februa y 26, 1905. Serial No. 247,320.

the ribbon; mechanism of visible-writing machines, 'by'which term is meant those machines in which the type-writing as :it iswritten is in-view of the operator. Insuch machines that portion of the ribbon between the ribbon-spools is usually controlled by a ribbon-vibrator, which term as herein employed comprehends any device for autoaway from the printing-point.

matically moving the ribbon to the printingpoint and for thereafter moving the ribbon T he vibrator or carrier normally positions the ribbon so as to leave the printing-point uncovered. Whenever. the type-actuating mechanism is operated, the vibrator in known. constructions isaffected so as to cause the ribbon to cover the printing-point on the platen. After an impression has been made the vibrator carries the ribbon back to normal position, leaving the printing-point uncovered. The continuous vibration of the ribbon carrier or vibrator during the operation of the machine is sometimes a source of annoyance to the operator. Furthermore, the vibrator itself and that part of the ribbon between the ribbonspools must be lifted at each printing operation, thereby increasing the amount of power which must be applied to the printing-keys in' order to obtain an effective operation of.

the printing mechanism.

The chief objects of my invention are to obviate these objections, and I do this by providing a mechanism which will cause the ribbon carrier or vibrator to be automatically actuated to cover the printingoint and to be retained automatically in t at position during the ordinary operation of the printing devices, the c arrier or vibrator automatically returning to normal position whenever the operator pauses in the course of the work.

To these and o'ther ends the invention reside's'in' the features of construction, combination of devices, and arrangement of parts,-

to be hereinafter more fully described, and particularly pointed out in the claims;

In the accompanyng drawings, Figure '1 is a vertical front to rear sectional view taken about centrally of a type-writing machine embodying my invention,'parts of the machine being omitted. Fig.-2 is zifragmentary front elevation of the machine. Fig. 3 is an enlarged side elevation, partly in section, of parts of the ribbon mechanism as they appear in normal position. Fig. 4 is a top plan viewof some of the'parts shown in Fig. 3, certain parts being shown in section. Fig. 5 is a rear elevation of some of the parts shown in Fig. 3; and Fig. 6 is similar to Fig. 3,

but showing the parts as they appear in printing position.

In the drawings, 1 indicates the base of the machine, 2 corner-posts, and 3 a top: plate mounted thereon. Key-levers 4' are fulcrumed on a fulcrum-plate 5, and each keylever is provided with a restoring-spring 6 and has pivoted to it at 7 a sublever 8. The

lower portion ofeach 'sublever 'coacts with a fixed abutment 9, and at its upper end each of said subleversis connected by a link '11 with a type-bar 1,2, which is one of, a segmentally arranged series. The type bars may, as shown, be pivoted on a curved fulcrum-wire 1.3 and guided in slots 14 in a segmental type-bar support 15, or each type-bar may be providedwith individual pivots and hangers. The type-bars cooperate with a platen 16, mounted in a Wriage 17, the latter being provided with. oppositely-grooved rails 18, which through antifriction-balls 19 coact with rails 20, fixedly attached to supports 21, secured to the top plate. The carriage 17 is provided with a feed-rack 22, which normally engages with a pinion 23, said pinion being operatively connected with an escapement-wheel 24. Adapted to cooperate with the escapement-wheel are feed-dogs 25, mounted in a pivoted dog-rocker 26, the horizontal arm 27 whereof is connected by a link 28 with the central rearwardly-extending arm 29 of a universal-bar frame 30, provided with a pivot-rod 31, having its bearings in the sides of the base of the frame.

' The universal-bar frame carries a universal bar 32, Which passes from side to side of the machine beneath the series of key-levers 4 and is adapted to be depressed by each of said key leversas it is :actuated' toicause 'itsiassoeiate type-bar 12 to print.

Any other suitable-manner of mounting the pivot-rod 73 in its bearin s may of course be ado ted. Secured to t e rod 73 in any suitab e manner, as b soldering, is a locking member 74, whic is disposed on said rod so as to .be in the'same vertical lane with thelip or lug 62 The 'partsiiare'so'arranged in order to avoid conflict or interference with a stationar pointer or'indicator, which codperates with the usual carriage-scale, neither the pointer nor the scale 'belng shown in the drawings. The locking member 74, as herein shown, is in the form of a latch, which terminates forwardly in a-tooth-like portion 75 and at its lower end is provided with a rearwardly-pro jecting lip or lug.7'6. A'li t coiled spring 77 surrounds the rod -73 an has one end secured in a side wall 54 and the other'end secured inthe locking member 74, said spring tendin constantly to press thetooth 75 toward't e body portion 47 of the ribbon-vibrator. The reariace of the body ortion 47 of the ribbon-vibrator is roughened or corrugated by pressing or otherwise, so as to -form a series of notches, serrations, or depressions 78, saidseriesrunning vertically of the ribbon-vibrator and being so positioned that the serrations'iwill be engaged by the latch 74. When the parts are in normal position, the lip 62, contacting with the lug 76, overcomes the pressure-of the spring 77 and holds the. latch 74 so that the toothed portion 75 thereof stands slightly away from the rear faceof' the body portion 47 of the ribbon-vibrator. Whenever a printing-kc 4 is depressed, the universal .bar is rotate downwardly about its ivot31, causing the link 68 throu h the stu 67 to swing the forward arm of t e operating-lever upwardly about the fulcrum 58, the extent-to which the arm is moved depending upon the position of the stud 67 in the slot 63. As the forward arm of the operating-lever 57 moves upward the lip 62 rising with it ceases to press on the lug 76v of the latch 74, allowing the spring 77 to press the toothed portion of the latch into contact with the rear face of the ribbon-vibrator. The continuation thereafter of the upward movement or the lip 62 .ries said lip out of contact with the lug 76 of the latch, since the latter is held from further rotation by the rear face 1.5 the ribbon-vibrator. As the forward arm of the operating lever 57 starts to I move upward the ribbon-vibrator is caused to move upward with it against thetension of the coiled draw-spring 64 by reason of the contact of the top edge of the hook 60 with the shouldered portions 48 of the vibrator. During this upward movement or throw of the vibrator the toothed portion of the latch enters the corrugations or serrations 78, the latter sliding over said toothed portion until the vibrator reaches the limit of its upward movement. When the limit of upward movement has been reached, the operatingf lever starts to return; but the ribbon-vibrator is prevented from returning with it; by reason of the enga ement of the toothed portion 7 5- of the latc with one of the corrligations or depressions 78, the particular depression depending upon the extent of the throw of the vibrator and that depending, as hitherto explained, u on the position of the stud 67 .in respect 0 the fulcrum v58 of the operating-lever. In Fig. 6 the parts are shown at the limit of upward movement, with the I toothed portion of the latch 74 in engagement with one of the lower notches 78 of'the series of notches, the stud 67 being positioned in the slot 63 by the eccentric 71, so as togive such a result. 'Moving downwardfrom the position indicated in said Fig. 6 under the influence of the -universal-bar-restoring spring, (not shown,) the hookportion IOO machine before the universal bar 32 has moved upward from its depressed position sufiicient y far to allow the lip 62 to contact with the lug 76 said universal bar will be depressed b the operator and will be swung downwar again, thereby causing the lip 62 to a ain move upward. The parts are so related universal bar has almost returned to normal position and the limit of the downward movement of the lip 62 has been reached that I 5 the ordinary speed with winch the machine the latter will contact with the lug 76. At

is operated the universal bar returning towar normal position after being depressed by one keg-lever will be met while still some I no and adjusted that it is not until the Y &

ted to return far enou h the lip contacts with the lug and pressing ownward on thelatter swings the tooth part 75 of the latch out of engagement with the depression 78 in the ribbon-vibrator. As the tooth 75 swings clear of the depressions 78 the ribbon-vibrator is instan tly pulled downward by the drawspring 64 until the shoulders 48 contact with the top of the hook 60. At thenext printing operation the ribbon-vibrator is moved upward, and the spring 77 moves the latch 74 so as to bring the tooth 75 thereon into engagement With one of the depressions 78, the particular depression depending upon the position of the stud 67 in the slot 63. The

' vibrator will stay at the printing position until the operator again pauses or operates the printing-keys slowly enough to lip fifi to contact with the lug 76 and disen gage' the latch from the vibrator. The parts may of course be so arranged and proportioned that the latch will be released by even a a slighter movement of the lip 62 than that indicated in the drawings.

By my invention the ribbon-vibrator is.

automatically actuated to printing position when a key-lever is depressed and stays at the printing position during the ordinary operation of the succeeding printing keys. When the operator pauses to inspect the work or for any other purpose, the vibrator is caused automatically and independently of its operating-lever to return to normal position, exposing the printing-point. The result is that during ordinary or rapid o eration the vibrator remains motionless at t e printingpoint, thereby relieving the operator after the first key. depression from applying power sufficient to lift the ribbon-vibrator itself, as Well as the length of the ribbon between the ribbon-spools, in addition to the power required to operate the type-actuating and escapement mechanisms. Furthermore, the annoying vibration of the ribbon-carrier or vibrator which occurs at each printing operation is obviated by the use of my invention.

Various changes in the construction and arrangements of the parts may be effected within the s irit of the invention.
